NAME
arpsnmp - keep track of ethernet/ip address pairings
SYNOPSISarpsnmp [ -d ] [ -f datafile ] [ -e username ] [ -s username ] file [ ...
]
DESCRIPTIONArpsnmp keeps track for ethernet/ip address pairings. It syslogs activity
and reports certain changes via email. Arpsnmp reads information from a
file (usually generated by snmpwalk(1)).
The -d flag is used enable debugging. This also inhibits mailing the
reports. Instead, they are sent to stderr.
The -f flag is used to set the ethernet/ip address database filename.
The default is arp.dat.
Note that an empty arp.dat file must be created before the first time you
run arpsnmp.
If the -e flag is used, arpsnmp sends e-mail messages to username rather
than the default (root). If a single `-' character is given for the
username, sending of e-mail is suppressed, but logging via syslog is
still done as usual. (This can be useful during initial runs, to collect
data without being flooded with messages about new stations.)
If the -s flag is used, arpsnmp sends e-mail messages with username as
the return address, rather than the default (root).
